Subject: scsi: megaraid: Convert timers to use timer_setup()

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. Also consolidates the timer setup
functions arguments, which are all identical, and corrects on-stack timer
usage.
